Baris,
Not sure what's happening there, in all honesty. Something's definitely not right but we haven't heard of that issue before. While it is possible it's the old version of Joomla, it's unlikely. My better guess is that it's some configuration error either with your server or PHP settings. Looking at the logs, I'm actually not seeing any Autotune requests for fetching new App recommendations, only a request to run the error checker tool.
Can you go to the Basic Info page of Autotune and re-verify your Subscriber ID? Also, at the bottom of the Autotune area, does it show your subscriber details, or does it say "No Subscription Found!"?
If none of the above helps narrow things down, would it be possible to pass along a super admin account so we can take a look? If so, you can Private Message me by clicking the arrow under my picture (<
) and hitting the mail icon.
Finally, I'm going to make the grand assumption that you have no intent of upgrading Joomla to the latest 1.5.27 release, correct?
Thanks,
Alex
